Howard Miller Grandfathers clock 461-853BS Mechanism jamming

[AnKing]

Not a clock guy and have no experience repairing clocks before. I'm trying to fix my floor clock that seemed to stop working after being transported to another location.

The problem:

Clock working for about 4-6 hours then stop.

Once I took the front face of the clock I realized that cables are not sitting straight in their grooves, which is probably due to weights being  removed while moved.

I disassembled the mechanism and put the cables back into their groves but this did not fix my issue(even tho i was able to get like 10 hours of runtime after this manipulation)

I took the mechanism out of the clock again and inspected it further. What appears to cause the jam is that the disc(shaped as number 6) that is attached to the hour arm(marked number 1 on the picture attached) during its rotation jaming the hour selector arm(number 2) for the chime behind itself. This creates enough resistanse for the mechanism to stop because the weight can no longer provide enough force. 

I seems like there should be some way of returning this arm back to top position when it reaches the bottom, but it does not happen. 

It almost seems like the 6-shaped disk is installed backwards, but after watching a lot of videos i concluded that it is not the case.

Not sure what am i missing here, but if i cant figure it out I might as well remove this hour selector so that the clock start working.

Hi     The part No 1 is the snail cam which governs the strike count by virtue of the fact that No 2 the rack tail which rides on the snail cam when the rack is released. Make sure that the snail cam is seated ok and when the rack is released (by hand) the tail drops onto the snail cam. on the snail cam there are a series of steps these govern the depth to which the rack falls, If you count the steps there shouls be 12 the deepest being 12  O clock . and the shortest being the 1 oclock any - miss-alignment,  like the rack tail falling behind the snail cam can cause a jam or a bind and the clock will not strike right especially if it drops into the gear.    On the rear of the movement there is a number ie  123-123  Is this movement a Hermle one  It looks like it.

Hi find attached extracts from the Hermle manual discribing the functions of the two train and the three train clocks , The 461-853 is indeed a hermle movement eight day cable driven movement.

Good instructions given watchweasol. It sounds like the removals were not that good.
